Ok so what's going make level 2

I just press ctrl d

With this level one selected here

And I was just little 2 on it open today

So just for the purposes of this tutorial that shift the player over to a start location of maybe here

Let's maybe change all of these graphics back here

Maybe not be purple but let's do full-time Game Dev till

I like that brand colours so we do that

Let's do a teal colour

Something like that would be good

I'm saying for this year

Teal colour

Increase the saturation

And it'll be a little bit messy right here bye

Overground here maybe your platforms as well

Select all of those is kind of

Artistic

You give me patient right

And I maybe you can get this game done alright so let's go to blue here

A girl

Awesome

It's pretty good

And

We don't really need to change the

Black foreground here looks fine looks like we missed one here it's ok

Use the eyedropper tool

Tuesday dark blue

In the final thing we want to do is just go to a camera this year

Thermal camera how much like this boy here and maybe go a little prayer in a little bit later

Alright so now

Level two

Rico

Maybe ship some things around so maybe move that are here and I know this is just for the purpose

This tutorial

If you delete

Dilip dad dad The Spinney here and

Razor this

Building here I don't know you guys get the portrait

What is changing this level for this tutorial

So we got bullied in the background

We're clearly another to write colour just changed

Awesome

Play make sure everything works

So now let's Create

Trigger double load this level for us

After we beat level 1

Another one here

What we're going to do is going to create a new empty gameobject

I'm going to add a box Collider 2D to it

It's going to be a Trigger

What's use the scale tool in just sort of scale is up pretty back here something like this

Just started to play a king

Absolutely 100-percent can't avoid

This little triggers on here

This object seem load Trigger

Shall we put that in to layer one here

Where the player can walk

There's no parallaxing are coming so they can we miss it

Ok so you see shark script

I'm really cold this scene load Trigger

James Cranswick shares par for the course of the unity that's ok

Lower trigger here

Game object we can actually just drag this year

And now we have the Script attached to a scene on trigger

Let's just be sure to make cmode trigger a prefab cos they were going to be using this all right every levels

Another level in we're going to have

Linear game where we can go from one level to the next from left to right

Ok let's go ahead in open up and see no Trigger

And you probably guessed it were going to use on trigger enter

Because I'm an idiot remember how the right ontriggerenter2d

Copy it from the attack box here or we can do it from the enemy or anything like that just copying

Delete the

Inside of this function here

Pseudocode anymore do it guys we just write this

The collider2d which is col col

Object equals

New player

Instant start game object

Then later seen that again that was seen

Manager

Start

Load scene ok

And then we're going to load the next scene which is Level 2

Perfect

Looks like automatically it added a scene management namespace here that's pretty cool I didn't know it did that

Assassin

So if you don't see that

Can you see a zigzag here

I got to do is show potential fixes

Enniskillen put that namespace in there which allows us actually love scenes

Now summer thinking the timer sometimes with no one allowed a different seen maybe level 3 A level four

Maybe another one or a main menu

Thinking that's awesome it's crazy variable appear serializefield

Give me a private string and loadscene string

And we just remove everything here

And then jump back in the Unity

Now we can specify which

Seen we're going to load

Tennis Wigan lower level

2

Let's go head in

That level 2 is added to a build

There we go that means we can load level 2 now

Play here

And see if it works

Let's go get a key

This game

I got the key here and avoid the enemy

Open it up and let's load level two

Perfect

Alright level 2 just loaded

That's awesome it's as you can see guys

We have a very simple game loop

Now we do have a problem if I collect 10 coins on other one

Entry level 2

The nearest Echoes back to 0

So we go to the next one here

It goes back to zero

Well

What if we wanted the player to be able to collect certain inventory items or maybe in

Is there a health or decrease their health or the amount of coins they have in take those stats

To the next level

Now sometimes in games like Donkey Kong you want everything to just disappear and you start fresh

On the next level I'm not really sure what you want for your game so I'm going to build out this tutorial

So that works for both

Permanent inventory

Taking out from one level to the other but also the ability to clear out that inventory if you want

Well if you recall inside of the new player

C sharp script all of our inventory is stored

Inside the script and includes the coins collected are hell my other items like that even

Our inventory dictionary so everything is stored inside of this script so the moment that

Load a new level it's going to destroy the player in the Script alongside of it so we need

To ensure that the player doesn't get destroyed when we load into a new level

We do that as we just go down the word start function here

In all we do is create a new line of code

That says don't destroy on load and then we just lost out this game object

Well that's great

That means that were not going to destroy the player but the problem is

If we load into a new level

There's a player in that level as well so that leaves us with two players

Another problem

So in order to ensure that we don't have two players

Once level 2 is loaded

Read actually destroy one player

That is not the original player right

So what we want to do is actually just jump into a new player script here

And let's see here maybe on start and we could say something like

If we find a game object

Cold player

Well we just destroy it

Let me explain your sounds right

50 magical find player

Then

We just destroy

Me I can't type today can I

Miracle

So basically what this means is that second player

Unravel 2

If we find a game object

Cold player meaning the original one that

Came into our new scene

Destroy Me destroy gameobject

Don't say that out in

Japan the level 2 and see if it works

Play I should be good right

Lips

Not good why is that

That's because it sounded self

So it destroyed itself

We definitely don't want that

This is also true for even level 1 if we go to level one

Viaplay

Destroy itself

Not good we don't want that

So how do we avoid this

Well what if we were able to rename the player

Say something like

Game object

That name

Equals new player

We Do It Like That

Will that work

Which shop in the unity in hip fly

Another one

Look we have a new name is called new player

But I think there's a problem here what is that

Well if we collect the key here grab the key

Jump into the new scene

Jokes that didn't work

Another boat named new player

So it's not actually gonna find anything called player in destroyed that

So here's what we need to do

We need to go ahead

And use a new function

Called a wake

This is unity's clever way of making things a little bit easier for us

Awake and start are basically the same

Assist awake cabins before start

It will always fire before start

I think about maybe you wake up for the day so you nearly was a person you hit play

He wakes up for the day

And then he starts ok so on wake

We need to search out

In find if there is a game object called new player I see this

But here

We're going to look and see if there is a game object called new player ok

What's that mean what the original player the one on level one

Is it a wake up

He's going to say

Is there a game object called new player in the scene

If there is

Destroy himself

Bad

Because were renaming

After awake

He doesn't have a chance to destroy itself

Ok

Another word the start function we remind ourselves

When we enter a new scene

The player I'm level 2

Will fire this when he wakes up

And he is going to find a new player

And he's going to destroy himself

Mercedes SLK play

And if it doesn't make sense guys that's ok

Because I'm going to go through it again just say it makes absolutely perfect sense

Outlook we are renamed to new player

It can be any name you want if you want to do player original or first player animal care but I'm going to

New player so it matches The Script

I've got my key was got a little to here

Perfect

Ok to look

Can you play a still there

Still got all of my inventory about 2 coins that's great

And

Noticed how there's no more player here

That player got destroyed

Because I cannot take a look at the Script

When the very first player on level 1

When he wakes up he immediately thinks is there anything called new player

Is there is anything called new player on this seen immediately destroy myself before doing anything

Else in The Script

I'm going to destroy myself

Because I'm not needed is already something out there called new player

Well

If it doesn't find anything cold new player

That means that this is the very first player

So I get a move on to the start function this is the next

Function that happens when you hit play

Just going to rename myself to new player

Ok I guess I'm the original player I'm gonna change my name it's going to be a new player

Then

When this player

Loads into a new scene

Another player in just for clarity here

Save this out

This player here

He's going to wake up

I'm awake

What you going to do

Is going to look for something called new player

Well

That old player from other one

He loaded into the scene his name is new player

Is the boss right he's in charge

Because

The level two player

Found that game object called new player

Bye-bye I get it I need to be destroyed

And none of it is going to fire

This ensures again two things guys

This ensures that the player doesn't get destroyed when loading into a new scene that's important because we want to save over

But it also ensures that we can test on level 2 if we want

Watch if we start a mobile 2 and a play

What happens

You just get renamed to new player

The means that he can go to another level he could take to clear the level 3

Causing level 3 player to destroy

Does that make sense

It doesn't recommend we watching this video it's definitely not a complicated subject

Not at all but it is weird and it's kind of abstract

You'll get the hang of it I promise

Now there's another problem here we will talk about in the next video

You notice that when we load into level 2 the camera doesn't know what to look at Bray

And also

The UI is confused

Show me the update those two things

So if we

Show battery level 2 in hip play here

You noticed the camera

Knows exactly what to follow

Because if we click on the virtual camera here

You can see follow is set to

Player

Because by the fault

We told it to

Before we hit play

Follow as a player

But if we load into level 2 from level 1

Remember because of the Script we just wrote

In the previous section

Destroying that target

So now

The camera

Has no idea what the follow

Because we destroyed the player associated would love to while entering this new player

So what we need to do is just basically tell this camera

Is virtual camera here

Right so we can actually do that with a new script

Ok so let's create a new script

Really call this

Scene

Camera

We don't want to call it just camera because honestly unity has stuff out of the box that uses the term

So seem camera

Just to make it a little bit more unique

To the cameras prefab and just drag

This new scene camera script

Under the main camera

The first thing I want to do is reference the virtual camera

Inside of this prefab

So what are we doing here

Generate

Serialised

Private

Virtual

Camera ok looks like we get cinemachine virtual camera look back

You really call it

Cinemachine

Camera

Alright

Sonos how it automatically add the namespace here

Using cinemachine

You don't see this

Go ahead and add this and that will allow us

Make changes

To the cinemachine virtual camera

Alright say that John back in the Unity

Inside of a camel's prefab hair ties

So what we can do is actually just

Drag

The virtual camera

To this for a slap here

And any cameras prefab we use without level 1 or level 2 is going to have this reference

So we can make adjustments

12 camera

From the scene camera script we have

Save that

What is double check and make sure it looks good

OK Google everything was great

What about level to take a look save that

Let's go to main camera here

Awesome

We have seen camera here as well and it's referencing its virtual camera

Awesome

What can we do now

We have access

Universal camera

What's double click on seeing camera here

I must think about something here

If

Inside of new player

Where destroying

That level 2 player

Doing it on a wig

Then technically if we do something in start

It's happening after a week right

So after we've destroyed that level 2 player

Then I guess what we can do inside a start with the right this pseudocode

Set

Cinemachine

Virtual can't type 400 camera

Target

To be the new player

How do we write that out with actual script

We could say

On start

Cinemachine virtual camera double click

Follow

And then all we got to do is set it to new player that instance

Transform

Let's make sure this works what it does will just do a quick recap

Everything

So let's hit play

And that start function is going to fire right now

And it's going to look for the new player instance there it is so

Change it change it still did The Script so it said it

To be

On the new player instant so kind of follow this

We could even just to show you

We could remove

This all together

So now it doesn't know what to follow but because we have that new script that happens on start when we hit play

It's going to find

The new player instance and start following

This loading a level 2 and see if it works

Perfect it does

Now it's actually it's not on the right side here because it's been confined

Be that polygon Cameron fighter

What it works

And that's exactly what we wanted

Just double check what exactly just happened

So here is the truth

When we immediately load into level 2

There's actually two instances of new player

So if this was inside of a wake and not start number awake happens before start

Is this was inside of a week

Unity with bow window what to do

Because it's inside a start in we've already destroyed

The level two player

Awake

Inside a start there's only one

Fire inserts

So we can immediately just said it to that player

The Masons guys I understand I know it a little bit confusing go ahead and watch this video again

Try and wrap your mind around

The sequence of events of what's happening

I got it and this is by far one of the most confusing part of making games and honestly I am

Working on the loading scenes portion of a game because there's kind of a lot of

Idiosyncrasies in weird sequences of events

For clarity here before we jump into actually changing the spawn location let's just

Quickly review with gone on here

So

The very first thing that happens in this game

At the very beginning when we hit play

We check and see if there's a game object called new player

Now

If you're starting on level 10 starting in any seen really and hitting the play button in the unity editor

There is nothing called new player

Why is that

Because immediately after this that's when we rename something to new player

Ok

To the very first player

You experienced this line of code but he won't destroy himself

Then we go to start and he'll just remind himself this is basically I'm saying I'm the boss and my name is new player

So when new player walks in the level 2

Level 2 player

He's going to destroy himself

Because he's not needed because the boss just came into the world

The guy who owns the game right

The protagonist the boss what do this level on said

I'm new player

You're not needed

Dad player on level to destroy himself

Therefore saving Oliver data from the original player from other one

Ok

And that's all because awake in Star happened at different times

Then we also created a script called seeing camera

And all were doing with this is were saying the moment that we start not awake but start

Start happens after a week

The moment we start

The game

I'm going to change

The follow target

Cinemachine virtual camera

To be

The new player instance

Now if we didn't destroy

Level two player and we had two instances of the player

Cinemachine would be very confused

Unfortunately

Because we destroy level 2 player in wake

Once we move on to start

He knows who to follow

It's important to note here guys

That's start

Doesn't have some kind of local sequence of events to see in camera

Start in a week in both scripts happen at the same time

So this awake script fires before this start and it fires before the start

It Moves onto this start here

And also the Script will run the start

Important to think of both of the start functions is happening in sequence after

Is awake

Function

I know that's confusing again this is not complicated

What is abstract in a bit weird so if this doesn't make sense I encourage you to watch this video just one more

Train wrap reminder around what's going on

The last thing we want to talk about when loading into a new scene is spawn sounds

We could just move the player around right and have him spawn here that sounds

What have you moved into level 2

You're moving a level 2

Is going to actually just stay exactly where he was in the previous scene

Does it play Now show you exactly what we're doing here

Ok

Salad

Take a look at the players current position

His position is Curley 18

60k 18 on the x-axis and 6 on the Y

If we run over here is a 20 up look

On the new level

He's at the same position

Unit 21

Nn6

Tell

You didn't respond and move

We really want him to move over here

That will be one of the spine

Tell the way you going to do this is

We could technically

Input values

Into a variable like a spawn position variable evektor to

But I find it easier actually just to create an empty gameobject

Call it

Spawn location

And then we can just move this

Around where we need the player to spawn

Somewhere about right here

Because they use this

On every single level

So now we have a game object called spawn location

We just go to our new player script

Are we going to do now is basically on start

See hear about right here we're just going to say transform that position = game on

That's fine

Is the average cased gamer bigger find spawn location

Transform

That position

So we're going to move the player

To the spawn location

That's great was straight out

Just for clarity here let's move the player somewhere kinda crazy so maybe like to put him at the 0 position

Just for cleanliness a crate

And he should spine

Three spawn location

Because we put that script

In the start function

Awesome

So he just Bond

Rayquaza spawn location was that's perfect

Well there's a problem though

Remember at the start function is going to happen one time when we start the game

So what we want to do is actually have this transformed at position

Equals to spawn location position we want this to happen after we load into the new seen as well

So how are you this footsie here

Well if we go to our

Simo Trigger

We definitely can put it here like this

Because we're outside of the new player script we need to make sure we reference new player that instance

Gameobject transform deposition

So now it's going to load the scene

Once you engage with the see no Trigger

And then I'm going to change the position of a player

In magic to the spine location

Of the next level

The thing is is that the moment we load a scene

Unity has to wait for this load to occur so literally the framerate will drop to zero until the

Scene is loaded in destroyed the Old scene

And then we're going to actually be able to find

The new spine location

Deposition the player

Balustrade

So first on start because of a new player script

It's going to send us to the spawn location again that's because of this right here

Any start functions of the new player script

And then when we get the key and go to the next level

He gets repositioned

Perfect

That's awesome everything wants to be working just fine now your notice we have

Some references issues here so we're going to address those in the next section

However

I want to make something Clear here

If we take a look

At the scene won't trigger we have this right here

This is actually a little bit redundant because

Pretty much doing the same thing in this script as well

So how can we make this a little bit cleaner

When we create a function

And call it

Public void set spawn position and replace inside of a new player script

Ok

And then we can just literally

Have the position change

Finding a spawn location

That way all we got to do is take this appear

In the start function set spawn position

Going to call that function for us

Do the same thing here as well

Make sure you do new player that instance

Set spawn position

The reason why we doing that guys if we ever wanted to change something about how a spawn a curse so for example

We wanted to animal play a sound effect we can go

No audio source won't talk about audio in another episode audiosource stop play sound

Spawn sound you know

If you wanted to do that we can just do a once in this function

NN

Anytime we set the spawn position of the player weather is on start appear

Or whether it's

Not occurring AC mode Trigger

Will have to write that twice

It's just referencing that one function

And also guys miss you open up the collectible script here and

We're gonna simply change this from collision gameobject name to remove this in with just going to simply

Use the Instance of the new player so new player

Instance Die game object

Here we go
